ACANTHACEAE 355 
purplish-brown leaves, not at all mottled. This form is much 
more abundant in the Philippines than is the one with the 
mottled leaves and is frequently planted in hedge rows. It is 
not a native of the Archipelago, but, judging from one of its 
native names, ternate, was probably introduced by the Spaniards 
from the Island of Ternate at the time when Ternate was 
controlled by the Spaniards. 
Illustrative specimen from Manila, Luzon, November, 1914 
(Merrill: Species Blancoanae No. 208). 
PSEUDERANTHEMUM Radlkofer 
Justicia gendarussa Blanco Fl. Filip. (18387) 14; ed. 2 (1845) 10; ed. 3, 1 
(1877) 19, ¢. 9, non Linn. =PSEUDERANTHEMUM PULCHELLUM 
(Hort.) Merr. in Philip. Journ. Sci. 7 (1912) Bot. 248 (P. bicolor 
Radlk., Eranthemum bicolor Schrank). 
This species is common and widely distributed in the Philip- 
pines at low and medium altitudes generally growing in thickets. 
About Manila it is commonly known by the Spanish name cinco 
llagas (five wounds), in reference to the five, prominent, dull 
purple spots on the corolia lobes. 
Illustrative specimen from Montalban, Rizal Province, Luzon, 
November, 1914 (Merrill: Species Blancoanae No. 726). 
PERISTROPHE Nees 
Justicia dalaora Blanco Fl. Filip. (1837) 14 (sp. nov.); ed. 2 (1845) 10; 
ed. 3, 1 (1877) 20=PERISTROPHE BIVALVIS (Linn.) Merr. In- 
terpret. Herb. Amb. (1917) 476 (P. tinctoria Nees). 
Fernandez-Villar réduced this to Dianthera dichotoma Clarke, 
to which Blanco’s description does not apply. It is, however, 
an exact equivalent of Peristrophe tinctoria Nees, for which 
P. bivalvis (Linn.) Merr. is an older name. The plant is com- 
monly known in the Visayan islands as dalaora, deora, etc., and 
is still used for dyeing as in Blanco’s time. 
DICLIPTERA Jussieu 
Ruellia contorta Blanco FI. Filip. (1837) 496 (sp. nov.); ed. 2 (1845) 347; 
ed. 3, 2 (1878) 278=DICLIPTERA CONTORTA (Blanco) comb. nov. 
Blanco’s species was retained by Fernandez-Villar as a 
distinct species, who transferred it to Peristrophe as P. contorta 
(Blanco) F,-Vill.; Nees in DC. Prodr. 11 (1867) 156 trans- 
ferred it to Hypoestes as H. contorta (Blanco) Nees, but neither 
of these references is at all satisfactory. A careful search in 
Bauang, the type locality of Blanco’s species, in February, the 
indicated month of flowering, has resulted in the discovery of 
but a single species that agrees at all with Blanco’s description. _
